Heath Consultants Odorator - Manual (Page 8)

iv
ANY TIME GAS IS BEING PASSED THROUGH THE ODORATOR THE POWER
SWITCH MUST BE TURNED ON. THIS WILL DILUTE THE GAS AT THE
EXHAUST PORT AND PREVENT POCKETS OF CONCENTRATED GAS FROM
ACCUMULATING.
100% L.E.L. IS APPROXIMATELY EQUAL TO 5% METHANE GAS BY VOLUME
IN AIR. AS LONG AS THE REFERENCE C.G.I. READS SAFELY BELOW THE
L.E.L., YOU SHOULD NOT HAVE ANY PROBLEM WITH A FLAMMABLE
MIXTURE BUILDING UP.
ANY SUSPICION OF A GAS LEAK BY UNEXPLAINED SOUND OR OPERATION
OF THE ODORATOR IS REASON TO IMMEDIATELY SHUT OFF THE GAS
SUPPLY VALVES AND THEN SEEK THE CAUSE.
If indoors, do not turn the ODORATOR on until a reference C.G.I. indicates the
environment is safe. Likewise, allow the ODORATOR to purge for at least one
(1) minute after a reference C.G.I. also indicates the environment is safe. The
ODORATOR is NOT DESIGNATED Intrinsically Safe and MUST NOT be used
in a confined space or hazardous location.
WARNING:
KEEP THE ODORATOR AWAY FROM OPEN FLAMES, INLET PRESSURE
SHOULD NEVER EXCEED 4 PSIG AND DO NOT OBSTRUCT OR BLOCK THE
INTAKE OR EXHAUST PORT.
CAUTION: BECAUSE OF INHERENT LIMITATIONS, LIQUID CRYSTAL
DISPLAYS SHOULD NOT BE SUBJECTED TO EXTREMES
OF TEMPERATURE OR HUMIDITY. IF THE INSTRUMENT
IS EXPOSED TO A TEMPERATURE BELOW FREEZING OR
ABOVE +49 O C (+120 O F), THE LIQUID CRYSTAL DISPLAY
MAY TEMPORARILY CEASE TO FUNCTION PROPERLY, AND
IN SOME CASES PERMANENT DAMAGE MAY RESULT. IT
IS THEREFORE RECOMMENDED THAT THE INSTRUMENT
NOT BE SUBJECTED TO EXTREME CONDITIONS SUCH AS A
CLOSED VEHICLE IN DIRECT SUNLIGHT OR CONTINUOUS
SUB-FREEZING TEMPERATURES.
USE AT ELEVATION:
THE ODORATOR SHOULD BE USED WITHIN 1000 FEET OF
ITS CALIBRATION ELEVATION FOR ACCURACY. A READING
CORRECTION CHART, FOUND IN APPENDIX C, MAY BE USED
FOR ELEVATION CHANGES GREATER THAN 1000 FEET.
